nit pick

[Ray Andrews]

This is as trivial an issue as one could imagine:

    test1()
    {
         typeset -a test1=(\
         "foo"
         "bar"
         "baz")
    }

    test2()
    {
         typeset -a test1=\
        ("foo"
         "bar"
         "baz")
    }

    $ test1; test2
    test2:2: invalid mode specification

... but it seems to me that as a matter of strict logic, since the 
backslash indicates line continuation I'd expect both of the above to 
work, that is, the opening parenthesis after the equal sign should be 
seen correctly either way.  Or is there a logical reason for the difference?

Line continuation does not remove leading spaces from the following line.

To paraphrase Bart,

That's

        typeset -a test1=(     "foo"
        "bar"
        "baz")


>         typeset -a test1=\

[...]

That's

         typeset -a test1=    ("foo"
         "bar"
         "baz")


The \<newline> sequence is a "line-continuation". It is
*removed*.

Note that you can also do:

typeset -a test1=(
  foo
  bar
  baz
)

Ah!  So it really is rigorously necessary.  Yes, that's just as it 
should be, I'm sloppily ignoring the spaces and there's can't be a space.

Thanks both.
